I started this topic to track and discuss challenges with getting the best performance out of the system. I usually test each setting a couple of times. 27-1-2025 Nvidia 571.96 DLSS 4.0 Installed the new drivers. 25-1-2025 Adjusted GPU Overclock Increased CPU PBO Scalar and reduced some of the GPU overclock to further increase fps and frametimes. Time will tell if it also stays stable on the MP-servers. 18-1-2025 Clean W10 Complete reinstall of W10 returned another 5fps and better frametimes. Over the years the system got bloated with all sorts of traces from old hardware that I upgraded (2x GPU and CPU) and software that I tried and not fully removed. The system is snappy and clean again! I considered W11, but there are too many bad stories out there, no clear advantage for AMD and GUI modifications with taskbar etc W10 is easier. The only thing I still notice is that it seems that when I hit the FPS limit some sort of trouble in FPS and frametimes appears. When I stay a bit below 90, like 88fps, it is more stable. 27-12-2024 Current Overclock settings 64GB ----- EXPO: ON (timings default as stated on the DIMMS) 9800X3D ----- Turbo Game Mode: ON PBO: +200 Curve Optimizer: -20, FCLK Infinity Fabric: 2200 UCLK DIV1 Mode: UCLK=MEMCLK, SCALAR 10X 4090 ----- Core Voltage: +100 Core Clock: +120Mhz Memory Clock: +900Mhz, Fan: Power Limit 133%, Temp Limit 84. This GPU overclock is stable and gives me 4-5 extra FPS, even when i am CPU bound. My setup Windows 10 - latest version - Windows 11 will not happen until I will get serious latency advantages. Motherboard: ROG STRIX X870E-E Gaming WIFI Systemboard VR Headset: Varjo Aero SSD for DCS and Windows, separated DCS Settings Most are set to the max. SSS, Secondary Shadows, SSAO, SSLR are disabled; they do not bring much visually. Visibility Range Extreme. I have Visible Range set to High. Increasing this further is not bringing much visual improvement and really takes away performance. MSAA Mask Size 0.42 is my sweetspot. Testing Setup and approach My Windows has been heavily tweaked and optimized and I am currently still running the same Windows I started with 5 years ago. I upgraded my systemboard, CPU and GPU a couple of times but did not reinstall Windows. I think at certain moments in the past I even went too far with tweaking and should have dialed back and better register what I was doing. So a clean install will be somewhere in the near future because I am certain I have left quite some performance on the table. For the basic quick test of setting adjustments or hardware/software updates I start a the default A-10C mission Runway Startup on the Marianas Map. I use Marianas because this mission is quite demanding and quite stable almost from the start with AI not doing much. I let it run a couple of times for 20 seconds and track the performance with CapFrameX to calculate the average FPS, 1% and 0.2% lows of the runs. Many other missions give me 90FPS, so adjusting settings with such missions will not give me noticeable visible differences. If I want to visually see the performance I open up the the FPS overlay inside DCS. I sometimes also open up the new XRFrameTools application to visualize my frametimes. Once a setting looks pretty okay I log into our Wing's Multiplayer server, startup OBS recording and give it a spin to see how it goes. I usually get 90FPS flat in this setup, while running OBS recording. Testing log From now on I will start adding my complete testing logs to this main posting. Where relevant I will add charts to visualize the difference between certain options. Certain tests were eye-openers. It was/is a dreadful process going through all the settings and quite a few settings were insignificant in my case. Frame Times, average FPS, 1% and 0.2% Lows My main goal is to find the ones that will bring more stability (reduction of intrusive stutters) and performance (increase of FPS/frametimes). Sometimes it is like searching for a needle in a haystack. Seeing the settings that made a difference might bring quick wins to others as well. Overall the average FPS is not improving that much by all the tweaking, it is easy though to screw up your system and reduce FPS. But once the FPS are pretty decent it is hard to get substantial improvements. My biggest wins are with the 1% and 0.2% lows, reducing these give a much better overall experience than to have 1-2 more average FPS. The overall FPS can be high, but when you have a few microstutters here and there it is very annoying and for me breaks the immersion in VR. Caution Please be careful, not all what works for me might work for you. Do everything at your own risk. I had some crashes, especially with the overclocking, so always make backups and restore points. I also don't have my overclock software start automatically anymore when tweaking, because that also caused an issue once causing me to keep rebooting into a crashing configuration. null null null

Hi guys, I´m trying to implement the new and recently released "dlssg-to-fsr3 (Replace Nvidia DLSS-G Frame Gen with AMD FSR3 Frame Gen)" from these guys in the link: NEXUSMODS_DLSSG to FSR3 That is supposed to implement frame generation even on Nvidia RTX 20 & 30 generation cards. It´s anybody here tried it jet? DCS doesn´t appear jet on their game compatibility list but we can start to trying on order to give some opportunities to a guys without the big pockets for RTX 40 series at this time? I just uploaded the latest released version in case somebody want to try it. Cheers, E.T. dlssg-to-fsr3-0.70-738-0-70-1703157519.zip

Just wanted to say thanks to team ED for delivering one of the best updates of the year with the introduction of DLAA/DLSS etc. I flew in VR online last night, something I rarely do in multiplayer due to the frame rate issues, and when i do i normally downtune the graphics and everything else to make it playable without stutters and freezes. Last night I forgot to do this adjustment, and it didnt care. The DLAA settings allowed smooth gameplay whilst maintaining visual fidelity, something I had to chose between before. Now it appears I don't! The new shadows are just superb, give a real depth to the environment which wasn't there before, and at times it was that good I could have said it was real. Some croppped VR screenshots. By far not the best visual quality you'll see, but for my 2080S to cope with a G2 at this grx setttings I am happy. Still going to get a 4080Ti though

Hey guys. Another topic about "building a new PC". My question is whether the VGA I'm choosing will work for what I want. My intention is to play at 2K and the setup I'm building is this: - i7 12700K - Gigabyte B660M Aorus PRO - 64GB (2x32GB) Kingston Fury Beast, 3200MHz, DDR4, CL16 - SSD 2 TB Kingston Fury Renegade, M.2 2280 PCIe, NVMe, 7300 / 7000 - Screen Asus TUF 31.5 LED 2K QHD, Curved, 144Hz, 1ms, VG32VQ with TIR 5 Most of the time I play multiplayer. Now the question: will an RTX 4070 Asus OC Edition NVIDIA GeForce, 12 GB GDDR6X, be able to run at 2K on a 31.5" screen with more than 60fps in multiplayer? Thank you for the patience. Seeya!

Hello all. I have HP Reverb G2 running DCS with OpenXR and MT binary. My PC has a 4090 and NVidia Drivers 545.84. If I start DCS in flat screen, DLSS is selectable. If I start in VR is greyed out. I disabled almost everything from OpenXR Toolkit, I tested with SteamVR also, but result is still the same. I attach my dcs.log. Any suggestion is much appreciated. Best regards. dcs.log
